BA3474WFV-CE2 Frequently Asked Questions (FAQs)

  • ROHM recommends a PCB layout with a thermal pad connected to a large copper area on the bottom layer to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • To ensure stable operation with a single power supply, ROHM recommends decoupling capacitors (e.g., 10uF) between VCC and GND, and using a low-ESR capacitor (e.g., 1uF) between AVCC and GND.
  • The maximum allowed voltage on the analog input pins is VCC + 0.3V. Exceeding this voltage may cause damage to the device.
  • While the BA3474WFV-CE2 is rated for operation up to 85°C, ROHM recommends derating the power consumption and using a heat sink to ensure reliable operation in high-temperature environments.
  • ROHM recommends checking the power supply voltage, ensuring correct pin connections, and verifying the clock signal frequency and amplitude. If issues persist, consult the application notes and contact ROHM support for further assistance.
